England captain Heather Knight (64*) got her side over the line in a closely fought warm-up fixture against the Board President's XI at the Wankhede Stadium, Mumbai.
The hosts - captained by Smriti Mandhana - batted first and were restricted to 154 after a disciplined bowling effort by England. Anya Shrubsole stood out with four wickets and Georgia Elwiss was also impressive, picking up 2-20 across her seven overs.
In reply, though, England struggled. They lost Tammy Beaumont, Amy Jones, Sarah Taylor and Nat Sciver early to leave them tottering at 11/4.
Knight found a patient partner in Danni Wyatt to advance the score to 60/4 but another flurry of wickets left the visitors in a spot of bother at 79/7.
Shrubsole and then Lauren Winfield helped Knight to get the job done for England, in a match that proved to be a stern test ahead of the first ODI.
England will take heart from their efforts with the ball, and will also be pleased to have come through with a win after a tough work-out.
Heather Knight: "It was great to get out there today and to get back into the rhythm of ODI cricket.
"It was nice to get a win under a bit of early pressure and it's given us some areas that we need to get better in before the series starts.
"The bowlers in particular had a good run out and put in some tidy performances.
"It's always great to be tested in warm-up games because it can help add that edge to your performance when you go into the series proper.
"The opposition played well today but we know there's more to come from us. As we've said, no England Women's team has won a bilateral ODI series out here so that's what we're working towards."
